AUTOMATIC PAPER-BAG FILLER.

SPECIFICATION forming part of Letters Patent No. 277,133, dated May 8,1883. Application filed March 2, 1883. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. HILL, ofthethe bags, and then place ittherein, and finally seal up said bags withtheir measured contents, thesaid machine being adapted to take the place of hand labor and increasethe capacity and reduce the expense of filling bags with seed, 85o.

In the drawings, Figure 1 is a side elevation of my improved bagfillingmachine with part in section. Fig. 2 shows a side elevation of part ofthe bag receiving and sealing apparatus. Fig. 3 is a section of part ofthe measuringapparatus, and Fig. 4 shows a perspective view of the formof paper bag used.

A is the frame. Y B is an inclosing-cylinder for the measuringwheel 0,and supports the seed-hopper B, which is provided with a scraper, b, ofrubber, wood, or a brush. The measuring-wheel G is supported on a shaft,0, and has one or more tubular orifices, 0 extending from the pe ripherytoward the center. In this tube an adjustable bottom, 0 is placed, whichmay be moved to or from the periphery by a screw, 0 and nut 0 supportedin a frame, 0 By this means the tube 0 may be adjusted in depth so as tomeasure off any desired amount of seed from the hopper B. The measuringwheel or cylinder may be rotated intermittently by a ratchet-wheel, O,secured to shaft 0, and provided with as many teeth as there aremeasuring-tubes in its periphery, and a pivoted pawl, G, pivoted to avertically-reciproeating bar, G, guided by hearing g, the said pawlbeing pressed against the ratchet-wheel by a spring,g. A spring-piece,Z), may be used I to press flat upon the teeth of the ratchetwheel, asshown, to prevent premature turning of said measuring-wheel.

' The bottom part of the case B is provided with a chute, B into whichthe seed from the measuring-wheel is intermittently discharged, and isretained therein until the propermoment by a bottom, B and slide-piece Ethe former being secured to a pivoted arm, B

hinged to a bracket, A, and is drawn upward to close the bottom of chuteB by a spring, A lug, 9 on red G strikes the arm B in its downwardmovement, and depresses thebottom B, as shown, to discharge the seedinto the bag held in cylinder E. 6

The bag-cylinder E is supported on a shaft, D, intermittently revolvedby any suitable means-as, for instance, a ratchet-wheel, D, with which apawl engages, the latter being reciprocated by a crank, D rotated by aband- 7c wheel, D and held against the ratchetwheel by a spring, d. Thisbag-cylinder, as shown, 7 has supports for six bags; hence it moves asixth of a revolution, and then comes to rest.

Secured, also, to the shaftD is a cam-wheel, 7 5

F, which has six projections, j, which actuate the pivoted lever F,hinged at its outer end to the bottom of the vertioally-reciprocatingrod G, thus imparting the requisite motion to the feed or measuringwheeland chute bottom.

N is the feed-table for the empty bags, and P the discharge-chute forthe filled bags.

The bag I, having flaps i, is fed into the flattened box E, carried bythe cylinder E, and

is then carried around one-sixth of a revolu- 8 tion and brought belowthe mouth of chute B The flap 2', resting against the sealing-bar 6"during its passage, receives paste from the brush h, attached to thepaste-vat H, and when brought to rest below chute B this flap is heldback by one or more spring-fingers, h. V1231; M ingtitsladvancement the,bag isopened by a I blast...ofitair fromcatnozzle, R, and fan R, andthe cam F then lowers the bottom 13 and slide 13 of the chute B bringingthe seed close to 9 3 the bag, and as the bag is brought to rest, thebottom still descends, the plate B remaining stationary, and dischargesthe measured seed into the bag, as shown in Fig. 1. As the cylinder Emoves on to repeat the operation the rec bar G is raised, closing thebottom of the chute just as it receives a fresh measured quantity ofseed, and simultaneously therewith the closing-plate e, guided by theslots j, is projected forward to close in the top of the bag, the saidmovement being effected by a bell-crank, .I, carrying on its free leg afriction-roller, J, which works against a cam-face, L, secured to theframe A between the chute B and discharge 1?. The plate 0 may be movedin and out by the cam, or may be withdrawn by a spring, j. While theplate 6 is advancing to close the mouth of the bag the sealing-bar e isthrown forward-in its slot is by the bell-crank K, carrying on its freeleg a friction-roller which works against the cam-face L. The pivotalpoint of the bell-crank K is pivoted to a radial bar, K held up againsta pin, 76, by a spring, K", and now that the mouth of the bag has beenclosed in and the flap has been turned partly over, the pivotedbell-crank K is drawn down by the cam M, causing the sealing-bar e to bedrawn toward the center of the cylinder E, being guided in theright-angled slot-s k, and thereby closes the flap z' and seals the bagtightly. As soon as relieved of the cams L and M the springs K and kbring the sealing-bar 0 back to its original place in the top of slot k,and allow the bag in its sealed condition to be discharged.

In place of the radial bar K guides for the pivot of the bell-crank Kmay be used, as shown at S. The closing-plate e and sealingbar e may beoperated by any other suitable mechanism.

v I do not limit myself to the particular construction shown, as it maybe modified in various ways without departing from my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
